What's the best YA novel of all time? The elite eight

Welcome to EW.com’s YA novel bracket game, a March Madness style tournament that will determine the best Young Adult novel of all time — as voted by you.

Down to the final eight, the matchups become tougher and tougher as The Hobbit battles To Kill a Mocking Bird, The Princess Bride faces Harry Potter, Perks goes up against the Uglies series, and The Hunger Games takes on The Fault in Our Stars. Which books will move on to the final four?

Check out the full bracket here before voting in Round 4 below. Polls close Sunday at 1 p.m. ET.

The Hobbit

To Kill a Mockingbird

The landmark fantasy novel that launched a million quests, dragons and dwarves optional. Not as bleak as grown-up successor-epic Lord of the Rings, the tale of Bilbo Baggins thrills and chill kids of all ages. – Darren Franich

A shortlist of great American novels would be incomplete without Lee’s Pulitzer Prize-winning coming-of-age tale, which revolves around scrappy tomboy Scout Finch. The novel’s setpiece is a racially-charged trial that Scout is almost too young to understand – though her retrospective recollections of it are anything but childish. – Hillary Busis

The Princess Bride

The Harry Potter series

Hello. This is a Renaissance era-inspired fairy tale of true love and adventure. You will fear the Dread Pirate Roberts and cheer for Buttercup and Westley. Prepare to read. – Shirley Li

An orphaned wizard attends a magical boarding school, makes friends, casts some spells and learns he is the one who must defeat bad guy Voldemort. Alongside a bunch of unforgettable characters – Snape! Hagrid! Sirius! Dumbledore! –­ Harry goes from an 11-year-old child to a 17-year-old man and, along the way, teaches us a bunch of lessons about love, kindness and bravery. The pop culture phenomenon spanned seven books and eight blockbuster films. – Erin Strecker

The Perks of Being a Wallflower

The Uglies series

Perks follows Charlie through his high school experience via letters he writes to an anonymous stranger. The heartfelt tale was made into a movie starring Logan Lerman and Emma Watson in 2012. – Samantha Highfill

Tally Youngblood lives in a post-apocalyptic world where looks determine the social order. The four-book series begins with Tally eager for her sweet sixteen, as it’s the age at which all citizens endure extreme plastic surgery to become part of the ‘Pretty’ class. – Jennifer Arellano

The Hunger Games series

The Fault in Our Stars

There’s a reason that Collins’ dystopian tale inspired a seemingly infinite army of post-apocalyptic imitators: It’s just that good. Brave, poverty-hardened Katniss Everdeen becomes an unlikely revolutionary when she volunteers to compete in the 74th Annual Hunger Games; the rest is blockbuster franchise history. – Hillary Busis

In this heartbreaker, teens Hazel Grace Lancaster and Augustus Waters meet in a cancer support group and fall in love. Prepare for tears ­ and a trip to Amsterdam to meet Hazel’s favorite author, the reclusive Peter van Houten. A film version, starring Shailene Woodley, hits theaters next summer. – Erin Strecker
